Product specification

2

× 0.7 W BTL audio amplifier with

output channel switching

TDA8547TS

DC CHARACTERISTICS

VCC =5V; Tamb =25 °C; RL =8 Ω; VMODE = 0 V; gain = 20 dB; measured in BTL application circuit Fig.4; unless

otherwise specified.

Notes

1. Measured with RL = ∞. With a load connected at the outputs the quiescent current will increase, the maximum of this

increase being equal to the DC output offset voltage divided by RL.

2. The DC output voltage with respect to ground is approximately 0.5VCC.
